Copy Url : https://www.koreawho.com/profile/ChoIWoohyung- Life Summary
Choi Woo-hyung is the CEO of VM.
He took charge of a company that had remained in the red for more than 10 years and led a complete turnaround, driving its growth.
He was born on September 2, 1967.
He graduated from the Department of Business Administration at Korea University.
He worked as a venture capitalist at KB Investment.
He recognized the potential of APTC (now VM), which possessed technological capabilities in the semiconductor etching equipment sector that had been monopolized by a small number of overseas companies, and actively invested in the company starting in 2003.
As VM struggled with equipment development and entered a period of management deterioration, he acquired the company in 2015 and stepped in to lead it directly.
He aims to develop and commercialize equipment based on domestic technology and grow the company into a comprehensive semiconductor equipment firm.
